Quick Answer \u2014 What is CJC-1295 without DAC?<\/h3>\n

CJC-1295 utan DAC<\/strong> (also called Mod GRF 1-29<\/strong>) is a synthetic modified GHRH (1-29) analog with a short ~30-minute plasma half-life. Unlike the DAC version, it lacks the albumin-binding tether, producing a pulsatile<\/strong> rather than sustained GH signal. This kinetic profile makes it the preferred research tool when pulse-timing matters. Supplied in 2\u00a0mg to 10\u00a0mg lyophilized vials for laboratory research use only.<\/p>\n<\/div>\n

What Is CJC-1295 without DAC?<\/h2>\n

CJC-1295 utan DAC<\/strong> (commonly called Mod GRF 1-29<\/strong> or simply tetrasubstituted GRF 1-29<\/strong>) is a synthetic 30-amino-acid analog of growth-hormone-releasing hormone. It shares the same core peptide sequence as CJC-1295 med DAC<\/a> \u2014 four amino-acid substitutions on the native GHRH (1-29) sequence provide resistance to DPP-IV cleavage \u2014 but lacks the albumin-binding DAC modification<\/strong> that extends half-life in the “with DAC” version.<\/p>\n

The practical consequence of no DAC: plasma half-life remains in the minutes-to-hours range (~30 minutes) rather than days. Research protocols therefore use multiple daily injections (typically 2\u20133x) to maintain GHRH signal rather than the weekly dosing of the DAC version. This mimics the short, pulsatile profile of endogenous GHRH and is the preferred research tool when pulse-timing matters \u2014 particularly in protocols studying physiological GH pulsatility alongside ghrelin-receptor agonists such as ipamorelin<\/a>.<\/p>\n

Molecular weight approximately 3,367\u00a0Da. Supplied as a high-purity lyophilized powder for reconstitution with bacteriostatic water. CJC-1295 without DAC is endast f\u00f6r laboratorieforsknings\u00e4ndam\u00e5l<\/strong> and is not intended for human or veterinary diagnosis or therapy. For mechanism, research context, and stacking protocols, see our Ipamorelin & CJC-1295 research guide<\/a>.<\/p>\n

Mechanism of Action \u2014 Pulsatile GHRH Signaling<\/h2>\n

Mod GRF 1-29 acts through the same pituitary GHRH receptor pathway as native GHRH, but with a kinetic profile that distinguishes it from both native GHRH and the DAC version:<\/p>\n
